This represents the eight black squares on the sides of an object (visible
when the object is selected). They are used as handles by the GUI to allow
for object move and resizes.
In the case of CreateFunc, this allows for the object to bind the mouse to
one or two handles while it's being created, so the user can place and size
a new object in one movement. See for instance
objects/standard/box.c/box_create() for an example.

You may want to have a look at Pierre Pronchery's work (originally in
French, partially translated into English); to my great shame, I have not
had yet the time to look at it in depth.
